Leakage-resisting square tunnel for prestressed concrete flexible sockets

Abstract

The invention relates to a leakage-resisting square tunnel for prestressed concrete flexible sockets. The leakage-resisting square tunnel comprises a square concrete body, a square steel wire mesh is arranged inside the square concrete body along the lengthwise direction of the square concrete body, a plurality of prestressed steel bars are evenly welded to the square steel wire mesh at intervals along the lengthwise direction of the square steel wire mesh, and a plurality of reinforcing ribs identical to the square concrete body in length and thickness are evenly arranged on the square steel wire mesh at intervals. Concrete members have prestressing force, so that leakage-resisting effect is good, connecting performance is high, vibration resistance is high, and waterproofness is good; the square steel wire mesh is arranged inside the square concrete body, the prestressed steel bars are welded to the square steel wire mesh, and the reinforcing ribs are arranged on the square steel wire mesh, so that the square concrete body is high in bending performance, less prone to cracking down and extruding to deform by soil, long in service life, fast in assembling, efficient and good in quality, and labor cost is greatly lowered.

Description

Technical field: [0001] The invention relates to an anti-seepage square culvert with a prestressed concrete flexible socket and socket. Background technique: [0002] The existing underground municipal facilities are subordinate to various departments, and each department is responsible for its own affairs. Cracks, or pipeline leakage, leakage and many other hidden dangers, especially the leakage of gas pipelines, are not easy to inspect and repair. During renovation, capacity expansion, and maintenance, the hardened ground of the road is often damaged, causing environmental pollution and resource waste. , traffic is blocked, businesses are damaged, and it also brings great pressure to road traffic. In addition, pipelines have a short service life, long maintenance and construction periods, high construction costs, and unguaranteed construction quality. Especially due to the influence of weather, it is difficult to carry out construction when it rains. The working environme...

AI Technical Summary

Problems solved by technology

[0002] The existing underground municipal facilities belong to various departments, and each department operates independently. The roads are dismantled, and the pipelines are either buried in the soil or penetrated into small underground culverts. There are many potential safety hazards such as cracking, or pipeline leakage, leakage, etc., especially the leakage of gas pipelines, which is not easy to check and repair. Renovation, capacity expansion, and maintenance often damage the hardened ground of the road, causing environmental pollution and waste of resources. , Passage is blocked, and business businesses are damaged, which also brings great pressure to road traffic

In addition, the service life of the pipeline is short, the maintenance and construction period is long, the construction cost is high, and the construction quality cannot be guaranteed. Especially affected by the weather, it is difficult to construct when it rains. The working environment of the workers is also poor, the efficiency is low, and accidents are prone to occur.

Furthermore, the construction involves many departments, such as roads, transportation, urban management, greening, etc., repeated excavation of the road surface, repeated road repairs, secondary pollution, and secondary hidden dangers
